HOT-WATER BOTTLE.

Specification of Letters Patent.

Patented June 27, 1911.

Application led September 21, 1910. Serial No. 583,082.

To all 'whom z't'may concern:

Be it known that I, DUMONT P. LAMB, citizen of the United States,residing Aat Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Hot-Water laoBottles, of which the following is a specification.

This invention relates to surgical appliances and accessories andcomprehends particularly an improved construction of hot water bottle.

The invention has for its primary object a simple and eflicientvhotwater bottle which will maintain as long as desired avconstant heatthrough the instrumentality of an electric current, and the inventionconsists essentially, in a hot water bottle with a chambei` for thereception of an electric light bulb which may be detachably connected tothe bottle whenever desired, whereby whenthe current is turned on, thewater in the bottle will be maintained at a constant temperature.

The invention also consists in a device of this character embodyingimproved means whereby the electric light bulb and socket may besecurely and yet detachably held in theybottle, the arrangement of partspermitting the bulb and socket to be readily applied whenever desiredand quickly detached from the bottle when the latter is not required foruse. And the invention also consists in certain constructions andarrangements of the parts that l shall hereinafter fully describe andclaim.

For a full understanding ofthe invention,

. reference is to be had to the following ldescription and accompanyingdrawings, m which:

Figure l is a perspective view of a hot water bottle constructed inaccordance with my invention; Figs. 2 and 3 are fragmentary sectionalviews thereof; and, Fig. 4t is a detail fragmentary view of the clampingdevice.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

My im roved water bottle may be formed of any esired substance ormaterial and may be of any desiredconstruction and de'- sign, exceptthat it is formed with a cham ber .l preferably opening at the bottom ofthe bottle and if desired having its walls lined with asbestos or someother similar material or substance, although I do not wish to belimited to the use thereof. The chamber l'may be of any desired size,although preferably relatively small, and is designed to recelve anelectric light bulb and socket 2, the same being held detachably in thechamber, so that the bottle may be detached from the electric lightsocket whenever desired and the latter applied to the bottle wheneverthe bottle is required for use.

ln the present embodiment of the invention, the means for detachablyholding the chamber bulb 2 in the socket 1 of thebottle consists ofclamping arms 3 and 4t, the arm 3 being preferably permanently connectedto the base of the bottle by having its ends embedded therein orotherwise secured, while the clamping arm 4C is pivotallyconnected tothe arm 3, so that one arm may be spread away from the other to permit.the electric light bulb and socket to 'be entered in the chamber 1 andthe swinging arm then closed around the relatively stationary arm tohold the bulb and socket in place. Preferably, the two arms 3 and 4: areformed intermediate of their ends with oppositely extending curvedportions 5 designed to snu ly surround the electric light socket 2 andold it securely in place, and

-to hold the arms in closed position relative to each other, l may useany form of clamp such as that illustrated at 6.

From the foregoing description in connection with the accompanyingdrawings, the operation of my improved hot water bottle will beapparent. ln the practical use of the device the arme is swung out fromthe arm 3 and the electric light bulb and socket 2 are then insertedinto the charnber l of the bottle and the arm d subsequently closed andfastened to the arm 3 by the clamp 6. rlhe current is then turned on,whereby the hot water in the bottle will, as isVV manifest, bemaintained constantly hot so long as the electric current is ermitted todow through the bulb and soc et 2. And preferably the relativelystationary arm 3 is formed at its ends wit lateral projections 7 thatare embedded in the wall of the hot water bottle and that are preferablywired, as indicated best in Fig. 2, so as to increase the bearingsurfaces and Qti tra

lll)

securely hold the clamp to the bottle. The arm 3 is only connected tothe bottle by these lateral projections 7. y

Having thus described the invention, what is claimed as new is:

1. As a new article of manufacture, a hot water bottle provided with achamber for the reception of an electric light bulb and socket, aclamping arm secured to the bottle and extending across the chamber,another clamping arm, the last-named arm being pivotally connected tothe first-named arm and the arms being designed to be clamped around `anelectric light socket, and means for holding said armsin clampingposition.

2. As a new article of manufacture, a hot water bottle provided with achamber' for the reception of an electric light bulb and socket, aclamping arm formed at its ends with lateral projections embedded in thewall of the bottle on opposite sides of said chamber, the arm extendingacross the chamber, a second arm pivotally connected at one end to thefirst-named arm, the arms being adapted to clamp around an electric.light socket, and means for holding said arms in clamping position.'

BIAS a new article of manufacture, the herein described hot water bottlerovided with a chamber for the reception o an electric light bulb andsocket7 a clamping arm fastened to the bottle and extending across theend of the chamber thereof and formed intermediate of its ends with acurved portion, and a complcmental clamping arm pivot/ally connected tothe first-named arm and formed with a correspondingly curved portion,the two curved portions being designed to encircle the socket of theelectric light bulb inserted in the chamber of the bottle, and a clampdesigned to secure the arms clamped around the electric light socket.

ln testimony whereof, l alix my signature in presence of two witnesses.

DUMONT P. LAMB.
